Abstract
River isotope automatic continuous sampling device of the present invention（Figure of abstract）Flow energy is assembled using funnel, water is drawn into road eminence by river course lower, avoids using outer power supply source, without water pump, cost is cheap, reliability and durability.Automatic sampling when device can realize water body flow, stop sampling during stagnation, meet that isotope sampling avoids the requirement of stagnant water.
Description
Technical field
The present invention relates to hydrology sampling tool field, specifically river isotope sample collection field.
Background technology
At present, application of the Hydrogen-oxygen Isotope Particle-beam Tracing in river runoff composition analysis is also more and more extensive, and river
Sampling then influences huge on isotope analysis result.Traditional river sampling method is usually sampling personnel periodically to taking on river course
Water, the river of a sampling period is represented with the water sample at a certain moment.But the river at a moment is to sampling period
River representativeness is very weak, especially on the river course that water quantity balance is complicated, change is violent, and shortens the sampling period and then often means
Heavy sampling work.River automatic continuous sampling can then greatly improve on the premise of sampling person works' amount is not increased
Sample significantly improves the reliability of analysis result to the representativeness of whole sampling period.
River sampler in the market is much, but commercially available sampler is typically realized by driven by power water pump, set up,
Use cost is high, it is difficult to is promoted the use of in areas without electricity.Subsampling device provides electric power by solar panel, and cost is more
Height, reliability are also poor.
The content of the invention
River isotope automatic continuous sampling device of the present invention, the energy of current itself is assembled using funnel, during water body flow
Automatic sampling, stop sampling during stagnation, meet that isotope sampling avoids the requirement of stagnant water.Device is without using civil power or solar-electricity
Pond, simple in construction without water pump, cost is cheap, reliability and durability, easy to spread.Sampler is mainly realized by following scheme：
1. met in straight river course to water (flow) direction fixed funnel one；
2. funnel afterbody connects PVC plastic hose one；
3. water sample is lifted above ashore filter by flexible pipe；
4. suspending sundries in water sample are filtered out by filter；
5. connection disposable transfusion device below filter, a barrel flow is entered by transfusion device regulation water sample；
6. transfusion device end is pierced into bucket top cover, the connection bend pipe that Open Side Down is to ensure to ventilate on top cover；
7. bucket is covered tightly with top cover, water sample surface Covering Liguid lubricating oil avoids Water Evaporation.
Brief description of the drawings
Accompanying drawing 1：River isotope automatic continuous sampling device figure；
Accompanying drawing 2：Funnel dimensional drawing；
Accompanying drawing 3：Filter detail drawing；
Accompanying drawing 4：Funnel suspension solutions figure.
Embodiment
1. funnel size is larger, it is necessary to tailor-made, it is copper or lucite preferably to select（PMMA）Or fiberglass（FRP）Deng machine
The higher material of tool intensity makes；
2. the preceding surface of funnel is covered with wire netting, aperture 2mm, in case debris blocks funnel or flexible pipe in water；
3. funnel fixed position should avoid slough, river course center is generally located on, fix bar should have certain elasticity,
Funnel is set to produce a certain degree of rock in order to avoid foreign matter blinds wire netting.Funnel is fixed on river course bottom by large-scale river course inconvenience
During portion, suspension solutions shown in accompanying drawing 4 can be used, but suspension, cable etc. should voluntarily be set according to river course situation, and funnel should increase extension
Ear, the strength of materials should suitably be strengthened, and weight quality should also adjust according to streamflow speed and weight material；
4. funnel end connection plastic flexible pipe internal diameter is 10mm, funnel afterbody is fixed on by strong adherence；
Current is flowed on filter 5. hose end is suspended on above filter, unnecessary water can outflow filter flow back to
River course, flexible pipe peak are not higher than river course water surface 2m；
6. filter is reequiped with medical 100ml infusion bottles, remove bottom of bottle, bottom fills up medical absorbent cotton, and 5 layers of pad is filtered on absorbent cotton
Paper, the quartz sand that filling particle diameter in filter paper top is 1-2mm, quartz sand top is covered with two layers of terylene filter cloth.Filter paper is a diameter of
150mm, must not be damaged, and outer rim is stretched out outside bottle, and terylene filter cloth is tightly secured in outside body together.Filter can be as needed
It is adjusted to other filters but should ensure that to be avoided that blocking transfusion device；
7. infusion set drop is 20（20 drops/ml）, bottle plug puncture unit is pierced into filter rubber stopper, and vein is needled into bucket top cover,
Regulation flow regulator makes flow velocity be 1 drop/min, and transfusion device model can also adjust as needed；
8. bucket capacity should be calculated according to the sampling period and set, capacity is not less than 3L when monthly taking a sample.Bucket material is height
Density linear polyethylene（HDPE）, sealing should be good in order to avoid foreign matter enters.Elbow downward linker is set on top cover, ensures bucket
Interior air pressure is not higher than ambient pressure；
9. interior of bucket pours into the thick lubricating oil covering water samples of 2mm in order to avoid water sample evaporates, cope level is less than filter bottom
Portion is to ensure that water sample smoothly flows into bucket.
Claims (4)
